A prevalence study of carotid atherosclerotic disease in patients aged above 60

The results of Doppler sonography and the echotomographic evaluation of extracranial arteries performed on 139 asymptomatic patients aged above 60 are presented. Atheromatous lesions were found in 54 (38.85%) of the subjects, though most had no hemodynamic effects. Statistical analysis showed an increase in both number and gravity of lesions with advancing age in females alone. No significant association was found between risk factors and atheromatous lesions, except for smoking in males.
